How To Choose A Machine Vision Filter


Machine vision filters are used to increase the contrast of the subject a camera is viewing, improving its ability to distinguish desired characteristics.

Increased contrast allows for increased accuracy and speed. Filters are selected by matching a filter type to the lighting being used and a filter size to the diameter of the camera lens.

About Our Machine Vision Filters

MidOpt specifically designs and manufactures filters for use with monochromatic or white LED lighting, fiber optic illumination, structured diode-generated light patterns and other lighting commonly used in machine vision applications. When matched with the correct lighting, filtering is one of the most important factors that controls the ability of an optical system to produce acceptable results.

We stock a wide variety of filter options designed to securely and quickly mount to the smaller diameter lenses used with CCD and CMOS cameras. Unlike most other filters that are sold as being for use with machine vision, MidOpt's filters are not only truly off-the-shelf and ready-to-use, but the filter material is also sized for each mount so that there is no restriction to the field of view.

Our Coatings:

  • Are extremely durable.
  • Are non-hydroscopic.
  • Do not require special care or handling.
  • Withstand repeated cleaning, solvents, high heat, humidity and vibration.
  • Have an almost unlimited life span.


Company profile


Midwest Optical Systems offers a complete line of mounted filters specifically created for industrial machine vision applications.

While many other companies offer unmounted or mounted filters developed for photography or other uses, these filters are often not readily adaptable to industrial vision equipment nor do they result in the best solutions for many machine vision problems.
